Channing Tatum is joining the cast of “Kingsman: The Golden Circle,” tweeting the news on Wednesday evening.

Sources also tell Variety that Elton John is in talks for a key role.

Matthew Vaughn is returning to direct from a script he co-wrote with Jane Goldman. The 2014 original, “Kingsman: The Secret Service,” was based on the comic-book “The Secret Service,” created by Dave Gibbons and Mark Millar, and follows the training of a potential secret agent to take on a global threat from Samuel L. Jackson’s Richmond Valentine.

Vaughn also produced the original, which grossed a surprisingly healthy $415 million worldwide. Colin Firth, Mark Strong and Michael Caine also starred.
